TV Show: Perfect Couples
Comedic claim to fame: Leigh (Munn) and her husband Rex are the most perfect (i.e. neurotic, cheesy, overwhelming, and obnoxious) partners among the show's three couples. At some point, you'll wonder what kind of meds she is taking, but at the end of each episode, you'll still want to get Leigh'd.
